For those of your who are slightly confused, FF 3.1 (that was supposed to be released in Decemberish) is called FF 3.5 now. I suppose that version number makes a bit more sense given the feature set and time frame.
Yep. I've always hated it when companies did the ole version =* 1.5 trick just to make it sound "better", but in Firefox's case, with a brand new JavaScript engine, built in HTML 5 <video> tag support, GeoLocation, and a few other big new features, I guess it does seem like a lot more than just a .1 increment.
